To all whom it may concern:

Be it known that I, MAURITZ C. INDAHL, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Matrix-Holders for Type-Casting Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings and the characters of reference Thisv invention relates to matrix holders for type-casting machines of the class well known as manufactured by Lanston Monotype Machine Company, the general organization of which machines is illustrated in the United States Patent No. 625,998, dated MayBO, 1899.

When a machine of this kind is equipped for composition, it. isprovided with a ma trix case, holding a number of matrices, provided at one end with a cone hole for centering the matrix in cooperation with the centering pin of the machine and usually with a typographic character impression in the opposite end. It sometimes becomes desirable to cast sorts from a single matrix of this kind, and for this reason a matrix holder has been devised for holding one only of these matrices this holder being adapted for use either when the machine is equipped for composition or when it is lacking certain elements necessary for composiare flat as compared with the cellular matrices above described, and are made by an r A holder of the process. last mentioned kind is illustrated in Patent No. 1193315dated August 1, 1916. A feature of this electro-matrix holder as 'compared with the previously mentioned cellular-matrix holder is that the electro-matrix holder proper is adapted to be slidably engaged witha sheath member which itself slides into the machine and is provided with ahook for attaching it to said machine. The first mentioned holder has this hook device attached to it rather than. to a separate sheath member.

An illustration of such The holder of the present invention is adapted to hold cellular-matrices, but it is also designed in its more limited form, to have the sheath feature of'the electro-matrix holder. When a castlng or composing machine has the sheath member secured in place, the machine is adapted for casting from a cellular matrix or from an electro-matrix, according to which matrix holder one may desire to insert into the sheath member.

' The cellular matrix holders which have been employed heretofore have been capable of holding only a matrix of definite dimensions, or at most matrices of a limited number of special dimensions. The present invention has for its object the production of a matrix holder ofthis kind which shall be. easily adapted for holding matrices of a variety of sizes. It consists,cenerally'speaking, of a main member or frame equippe with a handle, such member being slidable into the machine, or preferably, *into the above mentioned sheath secured in the machine, in which main frame there'is a matrix retaining supplemental frame, so supported in the main frame as to be readily removed from the main frame as a whole and substituted by another supplemental frame adapted to retain matrices of a different size. The removal of the supplemental frame from the main frame is a simple matter since it is accomplished preferably by merely removing a locking device. The invention also contemplates the of a holder embodying a frame of a plurality of members, one of which contains a cellv for retaining the matrix, and one of which members also is easily movable to a making position in which the matrix may be readily change from one matrix to another of the same size is a frequent one as compared with the change from one size of matrix to another s1ze,the latter being such as to require the removal of the supplemental frame from. the main frame.

In the accompanying drawings, illustrating a preferred form of matrix holder embodying the invention,

Figure 1 is a plan view of the holder;

Fig. 2 is a longitudinal section, on the line 22 of Fig. 1;

Fig. 3isv a front end view of' the holder; and

F ig.4 is a plan view of a portion of the holder eouippedwith a supplemental member, for retaining matrices of a different size from thoseof Fig. 1.

The main frame5 of the holder consists of a plate like structure, provided with parallelsides equipped with side guides or ribs 6, adapted to fit in the'guideways of the sheath member above spoken of or, of' the .usual die case frame of thecomposing machine. .The frameis provided with a leaf spring 7 upset near itsfree end to form a ,catch 8 and provided with a button 10 for engagement usually with the thumb when the hand-lell also attached to the frame is,

as is usual, grasped with the right hand.

The spring and its catch are so arranged thatin moving the holder into the machine the catch 8 will engage with apart of the sheath member so vas/to secure the main frame '5 in the machine with the matrix v in proper position for casting. Depressing -the catch 8 by moving the button 10 down by the thumb will release the main frame from the sheath so thatsaid frame maybe readily withdrawn from themachine. The

main frame is provided substantially cen- "trally thereofwithan aperture of generally rectangular shape to receive the supplemental frame.

The Y supplemental. frame consists, as

shown, of two block like members 9 and 9 the member 9 thereof being provided with a matrix cell notched in a lateral edge thereof, such cellbeing of the dimensions to retain a matrix of a desired size; the

second member 9 of the supplemental frame is adapted to abut against this edge of the 'firstmentioned cell member 9 so as to close the open side of the cell thereof. Both memberswhcnthus positioned accurately fit the apertureinthemain frame. A locking device in the form of a pin v12 is adaptedto pass throughalined holes in-the members 9;' and 9 of the supplemental frame near one end thereof so thatthe latter is locked in themain frame. The 'cell member 9 of the'supplemental frame maybe tilted upon this pin for example to a position. shown in dotted linesin Fig. 2 which ma-y becalled theg matrix extracting position, in which wporitiomthematrix ;may,.,be ,,inserted into or extracted from the cell. The member- .charaoter M; the plate16therefore serves 9 of the supplemental frame is held from tilting, however, by having its rear end cut away to form a tongue 13 extending under and being retainedbythe end of the leaf spring 7, as is clearly shown in Figs. 1 and 4E. The rearward ends of the supplemental frame members rest upon a shelf 14 extending from the main frame across the rear endof the aperture therein. There can be no downward tilting on the axis of pin 12 because of such seating of the rear ends of the supplemental frame members upon this shelf 14:. The tilting member 9 of the supplemental frame is also provided with laminated plates 15 and 16 shown particularly in Fig. 2 both plates being seated in a recess in the under side of said member 9 and being riveted thereto by the rivets 17. The lower plate 15 is provided with a notch corresponding with the matrix notch or cell in 85 the member 9 whilethe upper plate 16'has a smaller notch to correspond with the dimensions of the intermediate portions of the m atriX,-the latter beingindicated by the to retain the matrix from up and down movement in its cell. It is obvious that the matrix is adapted to be seatedin the cell by being slid laterally thereinto when memher. 9 is tilted to the dotted position of Fig. 2. The/pin 12 is provided with aknurled head. and, with a spring operated detent 18 the end of the detent engaging with the pin by seating in the groove 19 in the 'headthereof. A pull upon the'pi'n by the fingers will be sufficient to move the detent out of its groove and thus release the. pin so that it may wholly or partially bewithdrawn from the main frame to allow the supplemental frame to drop out ofithe main frame. When the proper supplemental members have been placed in the aperture in the main frame pin 12 maybe inserted by pushing it into the pin holes in the main and supplemental frames and the 'detent will automatically seat itselfin the groove 19 in the head of the pin so as to retain the pin in looking position and prevent its accidental removal.

. VVhenit is desired to use a matrix ofdif- 11 ferent, size from that for which the supplemental frame, shown in Fig. 1, is adapted,

a different supplementalframe is employed, for example a supplemental frame such as is shown in Fig. 4:, adapted for use with a matrix M of greater external dimensions than those of the matrix M of Figs land 2. The cell in the retaining member 9" of the supplemental frame (Fig. 4) is of suitable size to accommodate the matrix "M Moreover since the side walls of this matrix are all located distances from thecentering or cone hole m of the matnxiwhich differ from the correspondingdistances in the matrix M, and since thecone hole ebviously must necessarily be similarly located'for all sizes of matrices, the supplemental frame'members 9 and 9 may differ'in lateral dimensions and in the size and location of the matrix cell, although the width of the supplemental member over all corresponds in all cases with the width of the aperture in the main frame. For

example the member 9 of Fig. 4 is wider than the member 9 of Fig. 1, while the member 9 is correspondingly of less width than the member 9 moreover the cell for matrix M differs in dimension and location from that for matrix M. It will readily be observed that whatever size of matrix may be desired to be used, the present invention makes its fitting in the holder in accurate and proper location for casting a simple operation which cannot possibly be accomplished improperly. The matrix to be used must fit the matrix cell and when the proper cell member has been found to fit the matrix the proper abutting member of the supplemental frame must be found, else the supplemental frame. will not fit into the aperture of the main frame; a mistake in assembling is therefore impossible.

In Fig. 4. a modification is shown according to which a tubular extension 20 on the cellular member 9' of the supplemental frame which extension is coaxial with the retaining pin 12, extends through member 9 of the supplemental frame and is upset on its end so as to secure together the two members 9' and 9 of the supplemental frame at all times, although one may be tilted or moved to matrix extracting position without disturbing the other. When the two members are thus associated, it is ofcourse impossible to mix or confuse the members of supplemental frames. In this way a pair of members secured together forms a supplemental frame for a matrix of definite size and makes it impossible to make an erroneous assemblage of supplemental members.

When the matrix holderhas been inserted into the machine and a suflicient number of types have been cast from a given matrix, the holder is removed from the machine, and the matrix is extracted by merely tilting the cell containing member of the supplemental frame to the dotted line position of Fig. 2 and withdrawing the matrix by sliding it laterally from its cell. A new matrix of the same size may be laterally slid in the cell, the cell member allowed to fall back to normal position and the holder inserted into the machine. This change of matrices of the same siZe is obviously a quick and simple Operation. When it is desired to use a matrix of different size, the locking pin 12 is withdrawn and the supplementalframe is allowed to drop out. Another frame with a cell to accommodate the matrix is readily placed in the main frame aperture, the lock possibility of wrong assemblage or erroneous location of the matrix with respect to proper casting position.
